the lens has a very short serial number, only four digits 9168... in normal lenses 8 or 7 digits...the numbers are pressed into the body, which proves the authenticity...perhaps this is an esperental batch, or an error in the numbering, but this makes this lens one in a million

HELIOS"-44-2 2/58 it has a pre-installed diaphragm ring. It allows you to select one of the fixed values: F / 2, 2.8, 4, 5.6, 8, 11, 16. Unlike the preset ring, the aperture adjustment ring rotates smoothly and can be used to set any intermediate value. The smooth movement of the aperture ring is useful when shooting videos. The diaphragm consists of 8 blades that form holes in the form of regular polyhedra. 

The focusing ring rotates by 270 degrees (!), the movement of the ring is smooth. Aiming manually is quite convenient. During focusing, the front lens does not rotate, only the frame of the case is lengthened. HELIOS-44-2 2/58 it has a focus distance scale (only in meters) and a depth of field scale for F / 2, 4, 5.6, 8, 11, 16.

In the center of the image, the lens is quite sharp even at f / 2.0. With closed apertures, the edges and corners of the image return to normal.

Like other lenses of the HELIOS-44 family, the 44-2 version twists the background (the legendary" twisted bokeh " helios).

Lenses with M42 mounting thread (M42 X 1/45.5), such as the lens from this review, are very easy to use on almost any modern digital camera (both SLR and mirrorless), you just need to choose the right adapter for this.
